Title: Sensing and recording apparatus
IPC: G06K15/00
Filed: 1966-06-17
Abstract: 1,095,990. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATIONJune 17, 1966 [July 14, 1965], No. 27074/66. Heading B6F. [Also in Division G4]. In a pneumatic record card interpreter of the type disclosed in Specification 1,071,128, the zero-sensing module comprises a series of ducts 65-68 which co-operate with the perforations in a column of a record card 11 so as to pass air from manifold 37 to duct 69 only when there is a single perforation in the zero position, and a valve 70 is controlled, in zero-suppressed fields, to pass air pressure to zero print hammer 26 via duct 71 only when a sensed zero is significant. A disc 97 is perforated to connect aligned holes 96 in rotating discs 93, 94, when the first column of a zero-suppressed field is about to reach the zero-sensing module, so as to produce a pressure pulse in ducts 101, 106 and depress spool valve 103a, 103b, thereby blocking the connection between ducts 69, 71 via chamber 104. If the first column of the field contains a zero, 103a is raised, but 103b remains depressed and no zero is printed. Holes are provided in disc 97 to connect holes 95 in discs 93, 94 for the remaining columns of the field so that pressure pulses in ducts 102, 107 alternate with pulses in duct 69 in keeping 103b depressed, all the while non-significant zeroes are being sensed. When a significant, i.e. non-zero, digit occurs, the pulse in duct 69 is absent, and spring 105 raises 103b to reconnect ducts 69, 71 so that any subsequent zeroes are printed. Disc 97 is not perforated in positions corresponding to fields in which zero suppression is not required so that 103a, 103b remain in the position shown, allowing all zeroes to be printed.

Title: Improvements in or relating to tuned thermionic valve amplifiers
Inventor: PRICE THOMAS HENRY
IPC: H03F3/28
Filed: 1950-11-06
Abstract: 707,644. Valve circuits; phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 17, 1951 [Nov. 6, 1950], No. 27110/50. Classes 40 (5) and 40 (6). [Also in Group XXXVI] An amplifier comprises a pair of valves with a tuned output circuit consisting of a divided portion L1, C1, C2, C3 connected across the output electrodes and an undivided portion in the form of a variable inductance L2, which is included between the mid-point of the divided portion and the high-tension supply. Output power may be taken from across the push-pull circuit L1 &c. from across the circuit L2, Fig. 4 (not shown), from across a combination of the two, or from between either output electrode and ground, Fig. 3 (not shown). The amplifier may be of the grounded-grid type, and the cathode drive circuit may then comprise a network similar to that comprising the anode circuit. The arrangement may be used as an amplifier for phase or amplitude modulated signals. It may also be used to remove undesired amplitude modulation from phase-modulated signals in which case the valves are strongly driven and the output is taken from between either anode and ground. An output which is amplitude modulated in accordance with the instantaneous phasedifference between the inputs to the two grids may be obtained from across the circuit L2 or, alternatively, by means of a network bridging the two anodes. A further use is as a phase modulator; the grids are driven in phase opposition and the load across the circuit L2 is replaced by a circuit driven with an amplitude-modulated signal in quadrature with that applied to the grids: phase-modulated signals then appear between either anode and ground.

Title: Electrical compensator for the directional transmission or reception of wave energy
IPC: G01S1/02
Filed: 1930-09-12
Abstract: 362,534. Directional reception and transmission of wave energy. ELECTROACUSTIC GES., Werk Ravensberg, Kiel, Germany. Sept. 12, 1930, No. 27335. Convention date, May 20. Addition to 360,565. [Class 118 (ii).] The electrical compensator described in the parent Specification for use in the transmission and reception of wave energy is modified by dividing the contact strips transversely to their length, the various parts so formed being connected to a generator or indicator through separate retardation means. In Fig. 2, the strips 24 over which contacts connected to the oscillators are caused to slide are divided into two sections I, II. Each section is connected through retardation means 21, 25 and transformers 71, 72 to a generator 95 or indicator (telephone) 23. The dividing line L is so chosen that, on the average, the same number of receivers is in circuit with each retardation means. The secondaries of the transformers are so connected that the polarity of a transmitter or receiver does not change when its contact passes from one section of the contact strips to the other. Resistances 41 .. 49, 81 .. 89 are inserted in the compensator to prevent weakening of the signals by damping and by the absorption of energy from any one oscillator by the others. In Fig. 3, the invention is shown applied to a compensator used in transmission and reception in three dimensions in space and described in Specification 6095/31. The conducting strips 11 .. 20 are disposed on the surface of a sphere and are, according to the present invention, each divided into two sections, each section being connected to a retardation means. The contacts connected to the oscillators are disposed on a hemispherical shell movable about two perpendicular axes.

Title: Improvements in fine particle magnetic materials
IPC: H01F1/16
Filed: 1957-09-03
Abstract: Ferromagnetic material including aligned filamentary ferromagnetic particles having a length to diameter ratio in excess of 100 is made by intimately mixing powdered ferromagnetic particles with a non-ferromagnetic powder to produce a mixture containing from 5 to 75% of ferromagnetic powder by volume, compacting and sintering said mixture into a billet, and cold working said billet to elongate said ferromagnetic particles and to reduce the diameter thereof to one micron or less.  The ferromagnetic material may be Fe, FeNi, FeCo or FeNiCo, whilst the non-ferromagnetic powder, which has a fineness equal to or greater than that of the ferromagnetic particles, may be Ag, Cu or a non-alloying metal of low melting point e.g. Pb.  The compacting may be at a pressure of 20,000 p.s.i. and the sintering may be carried out in a hydrogen or other reducing atmosphere e.g. for 1 hour at 1700 DEG F.  The cold working may be in successive steps, e.g. one or more swaging followed by one or more drawings, with intermediate anneals at temperatures which avoid grain growth or coalescence e.g. for 1 hour in a hydrogen or other reducing atmosphere.  The wire so produced may be cut into lengths, collected into a bundle, sheathed in a silver tube, and then subjected to the same working schedule as before, or they may be hot pressed or sintered to produce a new billet for renewed working.  The non-ferromagnetic material may then be removed by means of a solvent, e.g. Ag may be removed by means of Hg or a 10% solution of sodium cyanide.  The fibrous aggregate may then be washed and either impregnated with a plastic and electrically non-conducting binder, followed or not by compression, or immersed in a plastic material such as a monomeric resin which is then polymerized.  A hard form of such a material may be used for permanent magnets, or a soft form as a magnetic core in an A.C. device.

A method of removing suspended liquid droplets, e.g. of oil, from a gas or vapour comprises causing the gas or vapour to flow in a multitude of fine streams between two mutually opposed surfaces defining between them, either alone, in which case at least one of the surfaces is of such configuration as to include portions which extend across the intervening space between the surfaces into contact with the opposite surface, or in conjunction with spacing elements interposed between the surfaces, a multitude of elementary channels of small crosssection along which the streams flow, at least one of said surfaces being absorbent to the liquid to be removed. As shown, a supply of compressed gas, carrying, e.g., a lubrication mist, is passed through a cylindrical pressure vessel 1 which is provided, at its ends, with gas inlet and outlet conduits, not shown, and accommodates a number of superposed oil-absorbtion units 2 separated by means of vertically-stacked spacers 3, 4 each comprising a cylindrical tube 3 with four metal wings 4 and which can be held together by means of a bolt and end-plates for closing the end of the structure. Each absorption unit 2 comprises rings 6, e.g. of felt, woven fabric, cotton wool, cellulose wadding, sintered metal &c., separated by rigid sheet-metal rings 5 having two sets of corrugations, Fig. 3, which are inclined to one another and lie in oblique relation to the direction of gas flow. The longitudinal axes of the channels of the two sides, respectively, of each layer of absorbent material may be inclined in respectively opposite directions to the direction of gas flow. The concentric rings 5, 6 may each be replaced by radially successive combinations of a spiral or helix and the spacing elements may consist of grains, strips, or filaments suitably spaced from one another.
